Toss Dental Paste contains Strontium chloride in a pleasantly flavoured base. Toss Dental Paste protects against sensitivity, fights cavities and plaque, fights gum problems and strengthens tooth enamel. It is used in sensitivity due to attrition and abrasion (wear and tear of teeth), natural gum recession or post scaling recession and abrasion on the neck of the tooth. All the ingredients in Toss Dental Paste block the nerve that carries the message of pain to the brain due to sensitivity. This protects the tooth and prevents the feeling of pain when eating and drinking. This toothpaste should be used on a regular basis for at least one month to get maximum benefit. Also massage some of the paste onto the sensitive areas after brushing.Directions for use:Brush properly twice daily for two minutes with this paste. Don't rinse after brushing for at least 30 minutes as it needs some time to work. By spitting thoroughly instead of rinsing the mouth with water after brushing, the thin coating of toothpaste remains on the teeth and provides the relief it is designed to give.
